Engineers hearing meeting showing economic decline (9)
I believe the answer is:
recession
'economic decline' is the definition.
'recession' can be an answer for 'decline' (I've seen this before). I'm not sure about the 'economic' bit.
'engineers hearing meeting' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'hearing' indicates a 'sounds like' (homophone) clue.
'meeting' becomes 'session' (session is a kind of meeting).
'session' sounds like 'cession'.
're'+'cession'='RECESSION'
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for recession that I've seen before include "Slump" , "Widespread decline in employment and trade" , "Period of temporary economic decline" , "falling back" , "Down-turn" .)
